Description
Technical field
The utility model relates to a kind of CVT buncher with down hill braking function, belongs to all-terrain vehicle speed change gear field.
Background technology
All-terrain vehicle environment for use is complicated, dangerous high, especially travels more in precipitous hill path, proposes requirements at the higher level to associated safety function.All-terrain vehicle CVT buncher structure is simple, volume is little, it mainly relies on driven wheel and belt to realize the electrodeless change of speed ratio, in the CVT buncher of existing all-terrain vehicle, its structure as shown in Figure 3, without engine down hill braking function, make to there will be the state of giving it the gun during vehicle descending, there is certain risk.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of CVT buncher with down hill braking function, this speed changer designs a kind of isolator device, make CVT buncher have down hill braking function, ensure that vehicle is in low-speed running state when descending is advanced.
The CVT buncher of band down hill braking function described in the utility model, comprise driving wheel and driven pulley, driving wheel is arranged on bent axle, driving wheel comprises active slip wheel and active fast pulley, driven pulley comprises follower slip wheel and driven fast pulley, described active slip wheel and the bent axle initiatively between fast pulley are axially set with isolator, between isolator two ends and bent axle, bearing is installed, belt is installed in isolator periphery, belt connects driven pulley, and isolator inner circumferential surface is provided with axial spiral gathering sill; The crankshaft section of described suit isolator is provided with steady pin, and steady pin one end is fixed on bent axle, and the other end is engaged in gathering sill.
Described bearing is ball bearing.
Operation principle and process:
When all-terrain vehicle extension forward gear is in descending state, during engine idling operation, belt inner surface contacts with isolator, because isolator inside is provided with screw type guide groove structure, when belt is subject to driven pulley power, under the effect of the inner gathering sill of isolator, isolator slides axially, belt is driven to change position, with the sheave contact friction of active fast pulley, thus generation frictional resistance, this frictional resistance ensures that CVT pulley can not turn faster and faster because of vehicle descending, ensures low vehicle speeds all the time.
The beneficial effect that the utility model is compared with prior art had is:
CVT buncher structure with down hill braking function is simple, and cost is low, easily realizes, and unique isolator design makes CVT buncher have down hill braking function, ensures that vehicle is in low-speed running state when descending is advanced, greatly improves security.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As Fig. 1, Fig. 4, shown in Fig. 5, with the CVT buncher of down hill braking function, comprise driving wheel and driven pulley, driving wheel is arranged on bent axle 7, driving wheel comprises active slip wheel 11 and active fast pulley 8, driven pulley comprises follower slip wheel 3 and driven fast pulley 4, active slip wheel 11 and the bent axle 7 initiatively between fast pulley 8 are axially set with isolator 5, between isolator 5 two ends and bent axle 7, ball bearing is installed, belt 9 is installed in isolator 5 periphery, belt 9 connects driven pulley, isolator 5 inner circumferential surface is provided with axial spiral gathering sill 12, 7 sections, the bent axle of suit isolator 5 is provided with steady pin 6, steady pin 6 one end is fixed on bent axle 7, the other end is engaged in gathering sill 12.
Hang forward gear when all-terrain vehicle and be in level road state, during engine idling operation, its CVT structure as shown in Figure 2, belt 9 is with initiatively fast pulley 8 wheel disc is contactless, hang forward gear when all-terrain vehicle and be in descending state, during engine idling operation, its CVT structure as shown in Figure 1, due to descending tyre rotation, by power transmission to power transmission shaft, power transmission shaft by power transmission to engine mission, in gearbox through gear mechanism by power transmission to driven pulley, power is passed to initiatively fast pulley 8 by belt 9 by driven pulley.Belt 9 inner surface contacts with isolator 5, because isolator 5 inside is provided with the reason of spiral gathering sill 12, when belt 9 is subject to driven pulley power, under the effect of the inner gathering sill 12 of isolator 5, isolator 5 relative sliding, thus drive belt 9 to change position, with active fast pulley 8 disk friction, thus produce frictional resistance, this frictional resistance ensures that CVT pulley can not turn faster and faster because of vehicle descending, all the time ensure low vehicle speeds, improve driving safety.
